A spark 36 is produced between two electrodes 33, 34, one of which is connected electrically to the mutually supporting faces 32 of the two piezoelectric elements 8 which can be compressed by means of a cam 18 linked to a lever 23. A gap E is left between the support faces 32 and the end of the electrode 34. A labyrinth 49a to 49d surrounds this end of the electrode 34 in order to isolate the latter electrically from two metal cheeks 2 connected to earth, and between which a cartridge 6 containing the elements 8 is mounted so as to be able to oscillate. Use for simplifying the mounting of electrodes. <IMAGE>
